SystemC clock time period

[Pruthvi Reddy G]

Hi All,

 

How to know the time period of clock in design module at ZERO simulation time i.e at end of elaboration  .Is their any API is available to know it ??

 

Thanks & Regards

If you use sc_clock to generate clock signal, it has a period() method that returns sc_time value for clock period:

sc_clock clk {"clk", 12, SC_NS};
cout << clk.period() << endl;

will print:

12 ns

If you design a clock source manually, you will need to create your own API for such queries.

Hi,

 

Thanks for replay.

 

If i bind that clk to my sc_in<bool>  clk.

 

i tried to print the clk.period(); it's giving error because sc_in don't have property of period function.

 

sudo code::

 

design.h ->

 

sc_in<bool> clk

 

void func(){

cout<<clk.period()<<endl;

}

 

 

in main file 

 

sc_clock clk{"clk",10,SC_NS)

 

object.clk(clk)

 

 

i tried this one..But it's giving error i.e period is not a member function

 

 

Thanks

sc_in<bool> is just a port, it has nothing to do with clock periods. You will need to pass a clock period value to your object some other way.
